[Feature Request]: Orbic RC400L - change LTE bands for Europe

### What problem does this feature solve or what does it enhance?

Can anybody explain to me, how I can change the LTE bands on Orbic RC400L?
Found this: https://forums.quectel.com/t/can-someone-explain-how-command-at-qcfg-band-works-ec200t/28400

How can I access via AT command port and change the LTE band configuration?
With a command like AT+QCFG="band" it is possible to change the LTE band.
How can I set the new string (0000000000000000000001A0080800C5) for europe?

Europe needs:

B1 (2100 MHz)
B3 (1800 MHz +)
B7 (2600 MHz)
B20 (800 MHz DD)
B28 (700 MHz APT)
B38 (TD 2600 MHz)

encodemask 1 3 7 8 20 28 38 40 41
0000000000000000000001A0080800C5
